2013 Mathematics game

Happy Year 2 0 1 3 !

The 2013 mathematics game is a neat game with numbers, suitable for many ages.


The basic idea is very simple: using the digits from 2013, form mathematical expressions for the counting numbers 1-100.

You have to use every digit 2, 0, 1, and 3. For example, number 5 could be formed as

(2 + 3) × 1 + 0 = 5

OR

(2 + 3) ÷ 1 + 0 = 5

OR

3! − 2 + 1 + 0 = 5


(3! is 3 factorial, which means 1 × 2 × 3)

You can even use decimals:

.2 /0.1 + 3 + 0 = 5

So, the task is to do this for numbers 1-100!
For smaller students, you could limit it to numbers 1-10.

Please see Denises's post for the full rules and other info.

Have fun!

Saxon Math is not for everyone

(Updated in 2018) People sometimes ask me of my opinion or review of Saxon math. What I've written here applies in particular to Saxon Math's high school courses and middle grade levels. (The grades K-3 are by a different author and are quite different; more on that below.) Saxon Math uses an "incremental approach" where math concepts are studied in little pieces over several lessons, and those lessons are strawed over a long period of time, intermixed with lessons about other topics. In other words, if one lesson is on some particular topic (say, percentages or inequalities), it's almost guaranteed that the NEXT lesson is NOT on that topic . It jumps around from topic to topic constantly, and this is by design. Saxon's method also includes a feature where after a lesson is taught, there are very few practice problems about the topic of the lesson. Most of the problems are mixed review problems, and they practice concepts from earlier lessons, not th...

Where do I start with Math Mammoth?

Where do I start with Math Mammoth? is a question I often hear (or read 😃 ). Most of the time, the best starting place is this page: https://www.mathmammoth.com/complete/placement_tests.php Looking over the tests will give you an idea of what is covered in each grade level of Math Mammoth. A natural next step is to administer a placement test or several (instructions for this process is explained on the page), but it's not always necessary to administer a test. Sometimes the teacher/parent can see just by looking at the tests, where the child would place. Often, the test reveals gaps, and you can use the TOPICAL books of the BLUE series to fill them in: https://www.mathmammoth.com/blue-series.php Or, you can use other materials you might have, or Khan Academy, etc. Sometimes it works out to use one of these review books to help a child get more solidified before starting a particular level in MM: https://www.mathmammoth.com/skills_review_workbooks/ https://www.m...
